摘要
针对多波段多光轴观瞄仪对光轴平行性检测需求,提出便携式高精度光轴平行性检测仪设计方案。为了减小系统的体积,光学结构采用卡塞格林式准直系统,运用Zemax光学设计软件设计并优化了其光学及结构参数。采用ZnS玻璃作为分划板基底材料设计了多波段共光轴的综合靶标,并利用CCD的感光面作为激光光斑采集靶面,提高了便携性,检测仪器检校光轴一致性偏差在±15″以内。实验分析结果表明:设计方案满足观瞄仪的高精度校轴和野外快速测试的需求。
To meet the requirement of optical axis parallel testing for multi-band and muhi-axis observation instrument, the design of portable high-precision optical axis parallel detector was proposed. In order to decrease the volume of the system, Cassegrain system was used as the collimating optical system, and the optical and structural parameters were designed and opti- mized by using optical design software Zemax. ZnS was used as the reticule glass substrate. Multi-band coaxial optical collaboration Target was designed and the photosensitive surface of the CCD was applied to collect the laser spot. The portability and measurement accuracy were improved. The consistency error of the testing instrument was within ±15＂. The experimental results show that the design meets the needs of the optical axis parallel measurement for the observation instrument with high precision and high speed in the outfield.
